Tuesday night's all new episode of the TLC docuseries marked Aaden, Alexis, Hannah, Leah, Joel, and Collin's 12th birthday party… which was a little awkward since only 5/6 of the sextuplets were actually there to celebrate!

With 16-year-old twins Mady & Cara Gosselin by her side to help decorate, Kate pulled off a pretty impressive scavenger hunt for her younger kids and their friends.

As you may be aware, Kate Gosselin and her kids — 16-year-old twins Mady & Cara and 12-year-old sextuplets Aaden, Alexis, Collin, Hannah, Joel, & Leah — are about to enter Season 5 of Kate Plus 8 on TLC.

Kate Gosselin was reportedly under investigation for alleged child abuse earlier this year.

As you know, the 41-year-old opened up about having to send her sonCollin, who has special needs, to a treatment facility to "help him learn the skills he needs to be the best him he can be" back in August.

Life & Style is now claiming that a source has come forward saying the 12-year-old admitted to a staff member that he had suffered abuse at the hands of his mother:

"Collin said something to the facility's staff and it was reported to Children and Youth Services [CYS], which started an official probe."

A person claiming to be a former nanny for the famous family told the outlet that Kate often got "physical" with 16-year-old twins Mady and Cara:

"Kate would spank her kids, especially the twins. The spanking was open-handed and was to discipline them if they wouldn't listen, but the kids would just cry more. They were scared. This would happen a few times a week."

It seems there's no lack of drama when it comes to Kate Gosselin and Jon Gosselin.

The formerly married couple are making headlines again as it's recently been revealed by InTouch that the momma of eight made shocking allegations against her ex in April of 2015.

According to their obtainment of police reports, Kate called the cops five times in three days over claims the reality TV star turned DJ "kidnapped" their daughter Hannah from school, was using his job as a "front to sell narcotics", "frequently" drank alcohol around the kids, and was being "suspicious" around their 10-year-old daughter.

And in a new interview published on Thursday, the college student admitted that she received a ton of hateful messages -- including death and rape threats -- following the crybaby candidate's digital tantrum.

The now-19-year-old explained to The Washington Post that she couldn't have anticipated the kind of backlash she received, saying:
